Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039866, here are decompositions:

29 + 1039837 = 1039866
43 + 1039823 = 1039866
67 + 1039799 = 1039866
97 + 1039769 = 1039866
103 + 1039763 = 1039866
199 + 1039667 = 1039866
263 + 1039603 = 1039866
313 + 1039553 = 1039866

Showing the first eight; more decompositions exist.
